<p>PROBLEM TO BE SOLVED: To provide a method for producing a metallic thin film with a low resistivity having excellent conductivity from a metallic fine particle-dispersed body by super heat steam treatment, and a printed circuit board produced by the method.SOLUTION: Provided is a method for producing a metallic thin film, including a process in which a coating film containing metallic fine particles is formed using a metallic fine particle-dispersed body on a heat resistant resin layer, and thereafter, heating treatment with super heat steam is performed, in which the thermal shrinkage of the heat resistant resin layer upon treatment at 350°C for 2 hr is 0.3% or lower.</p> |
